In the above image, large parts of the geometry and buildings have loaded in odd chunks and then they stay that way for 2-10 seconds at a time before loading properly. This happens nearly any time a building is loaded, or a new structure of any kind shows up, and it is so unbelievably ugly and immersion breaking that i have not been able to get past it. Has anyone else had this happen on pc? Does anyone know what causes this and how to fix it? Please help, i'd really like to be able to play this game but this is just so bad i can't bring myself to do it
